[Ah yes, the usual "we don't have the same word for this" issue. Victor tries to think of the best way to describe it.]

It's a musical instrument with strings and keys and hammers, all encased in -- well, I guess a kind of large box to be honest. When you press a key, the linked hammer hits the string and makes it make a sound. This "keyboard" somehow does the same thing with electricity. I've been playing ever since I was six.
